Yang plays a role of a queen for an ancient mining kingdom in the mountains, her scepter-sword being made from a rather sturdy and resilient gemstone, the gem and blade both being made from the material and strong enough to damage steel without a mar to the precious-stone. How it was cut is a secret to the smithy that was hired by the previous Queen for her daughter on her 16th birthday, the same day she began training herself to use a Wudan-similar sword-style (with the addition of a parry-mace tweak to the overall style).
